When it comes to performance tuning, the Subaru WRX and Mitsubishi Evo have long been contenders in the world of forced induction. Both vehicles are celebrated for their turbocharged engines, but the strength and durability of their engine internals can significantly impact their performance potential. This article explores how to strengthen the engine internals of the WRX and Evo 2.0L and 2.0T models for enhanced forced induction performance.
Understanding Engine Internals
Engine internals refer to the components within the engine that are crucial for its operation and performance. These include pistons, connecting rods, crankshafts, and cylinder heads. When tuning for forced induction, it’s essential to consider the strength and reliability of these components to handle the increased power and stress.
Subaru WRX 2.0L Internals
The Subaru WRX 2.0L, known for its boxer engine design, has unique characteristics that affect its performance. To strengthen its internals for forced induction, several modifications can be made.
Pistons
Upgrading to forged pistons is often recommended for WRX owners looking to boost horsepower. Forged pistons are stronger and can withstand higher pressures compared to stock cast pistons.
Connecting Rods
Strengthening the connecting rods is also vital. Upgrading to forged connecting rods can prevent failures under high-stress conditions, especially when running higher boost levels.
Crankshaft
The stock crankshaft can handle moderate power levels, but for serious tuning, a forged crankshaft is advisable. This upgrade ensures durability and reliability during high-performance applications.
Mitsubishi Evo 2.0T Internals
The Mitsubishi Evo 2.0T is known for its robust engine design, but it still benefits from internal upgrades when preparing for forced induction tuning.
Pistons
Similar to the WRX, upgrading to forged pistons in the Evo can significantly enhance performance. These pistons can handle the increased thermal and mechanical stress associated with forced induction.
Connecting Rods
Investing in high-performance connecting rods is crucial for the Evo as well. Aftermarket rods designed for high horsepower applications can prevent bending or breaking during aggressive driving.
Crankshaft
The Evo’s stock crankshaft can support a decent amount of power, but for those pushing the limits, a forged crankshaft is a wise investment to ensure reliability under extreme conditions.
Comparative Analysis of WRX and Evo Internals
While both the WRX and Evo have their strengths, there are notable differences in their engine internals that may influence a builder’s choice.
- Piston Design: The WRX features a unique boxer engine, while the Evo has an inline-four configuration.
- Strength of Components: The Evo’s stock components tend to be slightly more robust, but both benefit from aftermarket upgrades.
- Aftermarket Support: Both vehicles have extensive aftermarket support, but the WRX often has more options available due to its popularity.
Conclusion
Strengthening the engine internals of the Subaru WRX and Mitsubishi Evo 2.0L and 2.0T models is essential for maximizing performance under forced induction. By investing in high-quality forged components, enthusiasts can ensure their engines withstand the rigors of increased power and stress. Ultimately, both vehicles offer unique advantages, and the choice between them often comes down to personal preference and specific performance goals.
